Because money's value is based on its scarcity but government has the power to print (that is create) new money. And they have used that power to print new money for themselve…s. When it gets into circulation it inevitably drives up the price of everything. If money was linked to gold or silver then it would be impossible to arbitrarily create new money and its value would tend to be steady or actually increase over time.

Scientists look at the teeth of fossils of our earlier ancestorsand can see that they were omnivorous, just like modern humans.They have also found evidence of fossilised bone…s that were scrapedwith bone knives to remove the meat, something that only peoplecould have done. Life on Earth goes back some 500 million of the 4-5thousand-million years of the planet's own existence as far as canbe ascertained, but humans have been around for less than onemillion, though our nearer primate ancestors go back perhaps 4million. So the ages of the scraped bones would be tens or hundredsof thousands of years.

The answer to this would be basically the same way as today. Canada has an extensive highway system, railroads and many airports. So all of the different modes of transportati…on that were available back then are still in use today.

Honestly, I believe that EVERYONE was healthier about ten years ago than how they are now. Of course, there are exceptions, but the way that food products are being "produced"… doesn't really result in healthy people. Obesity is too common now and all sorts of eating disorders are all too common these days.

Less people die while on Mount Everest today compaired with fiftyyears ago because of many things. These include things like, havingup to date weather forecasts, better clothi…ng and climbingequipment and a better knowledge of the mountain.
